This was my thought exactly. What are the energy ratings on those older aluminum windows? What you think you are saving initially, may end up costing you even more, in the long run (with glazing heat loss).

Also, replacement windows are for installing in existing window frames. If it's a new construction home, you want to use new construction windows with nailing fins (with good Low-e ratings).
